How to calculate standard deviation

  1. Type or paste your numbers.
  2. Read the sample standard deviation, and the population one below it.
  3. Copy the results if you need them.

The formula

Find the mean, square each value's distance from it, add them up, divide by n − 1 (sample) or n (population), and take the square root. For 2, 4, 4, 4, 5, 5, 7, 9 the population standard deviation is exactly 2.
